1. Highlighted on page (Mozilla Firefox Add-ons (AMO) — Permission Prompt Comparison)
Permissions requested by Vezz me: activeTab, storage. Warning banner shown by Firefox on install: None (does not require 'Access your data for all websites').
Ctrl+Shift+X“Why does Vezz me not trigger the 'Access your data for all websites' warning in Firefox?”
2. Vezz me on-screen answer overlay
In Mozilla Firefox, the scary **'Access your data for all websites'** prompt is triggered whenever an add-on declares `<all_urls>`, `*://*/*`, or persistent `content_scripts` in its `manifest.json`.
Because Vezz me declares only **`activeTab`** and **`storage`** (with zero host permissions and zero background content scripts), Firefox's WebExtension sandbox guarantees that Vezz me is completely blind to your browsing until you explicitly press your shortcut (`Ctrl+Shift+X` by default).
3. Suggested follow-up questions in thread
- “How do I customize the shortcut in Firefox `about:addons`?”
- “Does Vezz me work inside Firefox Multi-Account Containers?”
